[0031] The present invention provides an air outlet structure.

[0032] In the embodiment of the present invention, Figures 1 to 6 As shown, the air outlet structure includes: a grille 10, the grille 10 is provided with a plurality of air outlet holes 11, and a plurality of wind shielding ribs 12 provided on the air outlet side of each of the air outlet holes 11, and two opposite side flow gaps 13 are formed between each of the wind shielding ribs 12 and the edge of each of the air outlet holes 11, and the side flow gaps 13 formed by two adjacent wind shielding ribs 12 are opposite to each other, so that the airflow flowing out of the two adjacent air outlet holes 11 flows in opposite directions through the side flow gaps 13.

[0033] In this embodiment, the grille 10 has an air inlet side and an air outlet side, and the wind shield ribs 12 are opposite to the air outlet 11 on the air outlet side of the grille 10. The specific shape of the wind shield ribs 12 is not limited, and it is only necessary to form a side flow gap 13 between the edge of the air outlet. It should be noted that the number and position of the wind shield ribs 12 correspond to the air outlet. The airflow enters the air outlet 11 from the air inlet side of the grille 10, and after flowing out of the air outlet 11, it flows out from the side flow gap 13 under the obstruction of the wind shield ribs 12. Since the side flow gaps 13 formed by the two adjacent wind shield ribs 12 are relative, the airflows flowing out from the two opposite side flow gaps 13 will collide with each other. The colliding airflows will form a dispersed flow and diffuse in the direction away from the grille 10, thereby achieving a windless air outlet effect. The scattered flow is formed by the collision of the airflow after flowing out of the air outlet 11, so it can reduce the attenuation effect of the air outlet 11 itself on the airflow, so that the airflow has sufficient flow rate and air volume when colliding, so that the scattered flow formed by the collision can diffuse faster and farther, improving the windless air outlet effect.

[0034] The air outlet structure of the present invention is achieved by arranging wind shielding ribs 12 on the air outlet side of the air outlet hole 11 of the grille 10, so that a side flow gap 13 is formed between the wind shielding ribs 12 and the air outlet hole 11, and the side flow gaps 13 formed by the two adjacent wind shielding ribs 12 are opposite to each other, so that the airflow flowing out of the two adjacent air outlet holes 11 can flow toward each other through the side flow gaps 13, collide with each other to form a scattered flow, and achieve a windless effect; since the scattered flow is formed by the collision of the airflow on the air outlet side of the grille 10, it can not only make the airflow fully flow out of the air outlet, but also improve the windless air outlet effect.

[0035] like Figure 2As shown, the plurality of air outlet holes 11 are arranged along the length direction and width direction of the grille 10, and the plurality of side flow gaps 13 are all oriented in the length direction or width direction of the grille 10. In this embodiment, the air outlet holes 11 are arranged along the plate surface of the grille 10, and the arrangement of the wind shield ribs 12 corresponds to the air outlet holes 11. The cross-sectional shape of the air outlet holes 11 can be circular or square, and there is no restriction here. The side flow gaps 13 can be oriented in the length direction of the grille 10 or in the width direction of the grille 10, and there is no restriction here. When the wind shield ribs 12 extend along the length direction of the grille 10, the side flow gaps 13 are oriented in the width direction of the grille 10; when the wind shield ribs 12 extend along the width direction of the grille 10, the side flow gaps 13 are oriented in the length direction of the grille 10. As a result, the side flow gaps 13 are also arranged along the length direction and width direction of the grille 10, so that the airflows blown out through the grille 10 can collide through the side flow gaps 13 to form scattered flows, thereby improving the windless effect.

[0036] like Figure 2 As shown, the size of the air outlet 11 along the length of the grille 10 is greater than its size along the width of the grille 10. The wind shielding ribs 12 span the air outlet 11 along the length of the air outlet 11 and form the side flow gap 13 between the two long edges of the air outlet 11. In this embodiment, the air outlet 11 has a certain length, and its length direction is consistent with the length direction of the grille 10. The wind shielding ribs 12 extend along the length of the air outlet 11 and connect to the two short edges of the air outlet 11, thereby forming the side flow gap 13 between the two long edges of the air outlet 11. This can increase the air flow outflow of the side flow gap 13, thereby increasing the amount of air forming the diffuse flow.

[0037] like Figure 2 As shown, the windshield rib 12 has two connecting portions 121 connected to the grille 10, with the distance between the two connecting portions 121 gradually decreasing along the air outlet direction. In this embodiment, the two connecting portions 121 are respectively connected to two opposite edges of the air outlet 11, and the distance between the two connecting portions 121 gradually decreases along the air outlet direction, forming a guiding slope in the air outlet direction. The guiding slope can guide and converge the airflow toward the center of the windshield rib 12, so that more airflow can flow out from the center of the side flow gap 13, thereby increasing the amount of airflow collision and allowing the airflow to form a more complete dispersion.

[0038] like Figure 4As shown, the windward surface of the windshield rib 12 forms a deflecting slope 122 that tilts away from the air outlet 11. In this embodiment, the windward surface, i.e., the side of the windshield rib 12 facing the air outlet 11, is spaced gradually from the middle of the windshield rib 12 toward the side flow gap 13, thereby forming the deflecting slope 122. The deflecting slope 122 can cause the airflow exiting the side flow gap 13 to tend to move away from the grille 10 before colliding with it. This allows the dispersed airflow formed after the collision to diffuse more quickly and fully in a direction away from the grille 10, thereby improving the airflow effect. It can be understood that the wind shield rib 12 and the air outlet 11 form two side flow gaps 13, so the windward surface of the wind shield rib 12 should also form two guide slopes 122. The two guide slopes 122 form an angle with the tip facing the air outlet 11, which can divert the airflow, so that the outlet airflow can flow more naturally and smoothly to the side flow gap 13 when passing through the wind shield rib 12, so as to reduce the loss of wind speed and air volume caused by turning.

[0039] Specifically, the grille 10 is bent along the width direction to form an arc shape. Therefore, on the one hand, the windward area of ​​the grille 10 can be increased to increase the number of air outlet holes 11 and wind shielding ribs 12, that is, the number of side flow gaps 13 is increased to improve the air outlet volume; on the other hand, the grille 10 can be made more compatible with the shape of the air outlet of the air-conditioning indoor unit to improve the integrity of the air-conditioning indoor unit after the grille 10 is installed.

[0040] like Figure 1 and Figure 3 As shown, there are multiple grilles 10, which enclose a wind passage 14 having an air inlet opening. The wind-shielding ribs 12 are provided on the side of the grilles 10 facing away from the wind passage 14. In this embodiment, the air inlet opening faces the air outlet of the air conditioner indoor unit. Airflow from the air inlet opening into the wind passage 14 initially flows toward the grille 10 opposite the air inlet opening. Due to the limited airflow capacity of a single grille 10, some of the airflow will be diverted to flow toward other grilles 10, ultimately flowing out through the side flow gaps 13 on each grille 10 to form a diffuse flow. This increases the overall airflow capacity of the air outlet structure and increases the diffusion direction of the diffuse flow, further enhancing the windless effect.

[0041] like Figure 1 and Figure 3As shown, the plurality of grilles 10 include a first long grille 15 opposite the air inlet opening, a second long grille 16 and a third long grille 17 respectively connected to the two long sides of the first long grille 15, and two short grilles 18 connected to the side edges of the first long grille 15 at both ends. The air outlet structure also includes connecting rods 20 connected to the two short grilles 18 for connecting to the air conditioner indoor unit. In this embodiment, the first long grille 15, the second long grille 16, and the third long grille 17 all extend along the length of the air outlet, and the three sides of the short grilles 18 are respectively connected to the ends of the three long grilles 10. There are two connecting rods 20, each connected to the two short grilles 18. One end of the connecting rod 20 is connected to the side panel of the short grille 18 adjacent to the air inlet opening, and the other end is connected to the air conditioner indoor unit, thereby fixing the air outlet structure relative to the air conditioner indoor unit.

[0042] like Figure 1 and Figure 3 As shown, the mounting end of the connecting rod 20 is bent toward the second long grille 16, and the width of the second long grille 16 is smaller than the width of the third long grille 17. In this embodiment, the connecting rod 20 is rotatably connected to the air conditioner indoor unit to drive the air outlet structure to rotate along the width direction of the air outlet, thereby allowing the air outlet structure to rotate between an air guide position and a storage position. The storage position is located within the air outlet. When the air outlet structure rotates from the storage position to the air guide position, the air outlet structure as a whole rotates toward the second long grille 16. To prevent the second long grille 16 from colliding with the housing of the air conditioner indoor unit, the width of the second long grille 16 should be smaller than the width of the third long grille 17 to avoid the housing of the air conditioner indoor unit during rotation, thereby improving the stability of the rotation process.

[0043] like Figure 5 and Figure 6 As shown, the air outlet structure further includes a microporous plate 30 disposed on the air inlet side of the grille 10, with a wind passage space 31 formed between the microporous plate 30 and the grille 10. In this embodiment, the grille 10 can be provided as an arc-shaped plate, with the microporous plate 30 disposed on the concave arc side of the grille 10, and the wind-shielding ribs 12 disposed on the convex arc side of the grille 10, so that the side edges of the grille 10 can be directly connected to the side edges of the frame plate, and the concave arc surface of the grille 10 can directly form the wind passage space 31 between the plate surface of the microporous plate 30. The microporous plate 30 is provided with micropores, which can pre-weaken the wind speed of the airflow entering the wind passage space 31, so that the diffuse flow velocity formed after the airflow flows out of the side flow gap 13 is even smaller, thereby further improving the windless effect.

[0044] The present invention also provides an air conditioner indoor unit, comprising a housing and an air outlet structure. The specific structure of the air outlet structure is described with reference to the above-described embodiments.
